Discussion

Nonlinear dynamic simulation reveals flexible wind turbine blade behavior under various conditions, suggesting effective modeling strategies.

The model maintains blade deformation accuracy under dynamic conditions, supporting effective design.
Errors in blade tip deformation were kept within 5% under gravity and 8% under wind loads, ensuring reliability.
Utilizing the Absolute Nodal Coordinate Formulation, the analysis employed 1D beam elements to capture complexities.
The results highlight potential for optimizing wind turbine design, despite challenges in simplified calculations.

Zhu et al. (2025) studied this question.
